Question

pls answer.. i will give the brainliest answer

Answer 1

Okay I'm doin' the 1st and 5th part for you to understand...!!

(a) 8x²y - 12x^5

⇒4x²(2y - 3x³) [We have taken common in this step]

And that's the answer to this, now (e)...

(e) 2n² + 5n -3

Well,here you first need to break the 5n part such that its sum is equal to original number and the product of cofficients is equal to the product of cofficient of x² and Constant.... Lemme show you

= 2n² + n - 6n -3

= n(2n + 1) - 3(2n + 1)

= (2n + 1).(n - 3) [Ans]

Note : For every such Question you need to go by this method...!!
